Within the age of knowledge overload, it’s straightforward to get misplaced within the great amount of content material accessible on-line. YouTube presents billions of movies, and the web is stuffed with articles, blogs, and tutorial papers. With such a big quantity of information, it’s usually troublesome to extract helpful insights with out spending hours studying and watching. That’s the place AI-powered internet summarizer involves the assistance.
On this article, Let’s make a Streamlit-based app utilizing NLP and AI that summarizes YouTube movies and web sites in very detailed summaries. This app makes use of Groq’s Llama-3.2 mannequin and LangChain’s summarization chains to supply very detailed summaries, saving the reader time with out lacking any focal point.

Goal and Advantages of the Summarizer App
From YouTube to webpage publications, or in-depth analysis articles, this huge repository of knowledge is actually simply across the nook. Nonetheless, for many of us, the time issue guidelines out shopping by means of movies that run into a number of minutes or studying long-form articles. In accordance with research, an individual spends only a few seconds on an internet site earlier than deciding to proceed to learn it or not. Now, right here is the issue that wants an answer.
Enter AI-powered summarization: a way that enables AI fashions to digest massive quantities of content material and supply concise, human-readable summaries. This may be significantly helpful for busy professionals, college students, or anybody who needs to rapidly get the gist of a chunk of content material with out spending hours on it.
Elements of the Summarization App
Earlier than diving into the code, let’s break down the important thing components that make this software work:
- LangChain: This highly effective framework simplifies the method of interacting with massive language fashions (LLMs). It gives a standardized option to handle prompts, chain collectively totally different language mannequin operations, and entry a wide range of LLMs.
- Streamlit: This open-source Python library permits us to rapidly construct interactive internet functions. It’s user-friendly and that make it excellent for creating the frontend of our summarizer.
- yt-dlp: When summarizing YouTube movies, yt_dlp is used to extract metadata just like the title and outline. Not like different YouTube downloaders, yt_dlp is extra versatile and helps a variety of codecs. It’s the best alternative for extracting video particulars, that are then fed into the LLM for summarization.
- UnstructuredURLLoader: This LangChain utility helps us load and course of content material from web sites. It handles the complexities of fetching internet pages and extracting their textual data.
Constructing the App: Step-by-Step Information
On this part, we’ll stroll by means of every stage of growing your AI summarization app. We’ll cowl establishing the setting, designing the person interface, implementing the summarization mannequin, and testing the app to make sure optimum efficiency.”

Importing Libraries and Loading Setting Variables
This step entails establishing the important libraries wanted for the app, together with any machine studying and NLP frameworks. We’ll additionally load setting variables to securely handle API keys, credentials, and configuration settings required all through the event course of.
import os
import validators
import streamlit as st
from langchain.prompts import PromptTemplate
from langchain_groq import ChatGroq
from langchain.chains.summarize import load_summarize_chain
from langchain_community.document_loaders import UnstructuredURLLoader
from yt_dlp import YoutubeDL
from dotenv import load_dotenv
from langchain.schema import Doc
load_dotenv()
groq_api_key = os.getenv("GROQ_API_KEY")
This part import Libraries and masses the API key from an .env file, which retains delicate data like API keys safe.
Designing the Frontend with Streamlit
On this step, we’ll create an interactive and user-friendly interface for the app utilizing Streamlit. This contains including enter varieties, buttons, and displaying outputs, permitting customers to seamlessly work together with the backend functionalities.
st.set_page_config(page_title="LangChain Enhanced Summarizer", page_icon="🌟")
st.title("YouTube or Web site Summarizer")
st.write("Welcome! Summarize content material from YouTube movies or web sites in a extra detailed method.")
st.sidebar.title("About This App")
st.sidebar.data(
"This app makes use of LangChain and the Llama 3.2 mannequin from Groq API to supply detailed summaries. "
"Merely enter a URL (YouTube or web site) and get a concise abstract!"
)
st.header("Methods to Use:")
st.write("1. Enter the URL of a YouTube video or web site you want to summarize.")
st.write("2. Click on **Summarize** to get an in depth abstract.")
st.write("3. Benefit from the outcomes!")
These strains set the web page configuration, title, and welcome textual content for the principle UI of the app.
Textual content Enter for URL and Mannequin Loading
Right here, we’ll arrange a textual content enter area the place customers can enter a URL to research. Moreover, we are going to combine the mandatory mannequin loading performance to make sure that the app can course of the URL effectively and apply the machine studying mannequin as wanted for evaluation.
st.subheader("Enter the URL:")
generic_url = st.text_input("URL", label_visibility="collapsed", placeholder="https://instance.com")
Customers can enter the URL (YouTube or web site) they need summarized in a textual content enter area.
llm = ChatGroq(mannequin="llama-3.2-11b-text-preview", groq_api_key=groq_api_key)
prompt_template = """
Present an in depth abstract of the next content material in 300 phrases:
Content material: {textual content}
"""
immediate = PromptTemplate(template=prompt_template, input_variables=["text"])
The mannequin makes use of a immediate template to generate a 300-word abstract of the supplied content material. This template is integrated into the summarization chain to information the method.
Defining Operate to Load YouTube Content material
On this step, we are going to outline a operate that handles fetching and loading content material from YouTube. This operate will take the supplied URL, extract related video information, and put together it for evaluation by the machine studying mannequin built-in into the app.
def load_youtube_content(url):
ydl_opts = {'format': 'bestaudio/greatest', 'quiet': True}
with YoutubeDL(ydl_opts) as ydl:
data = ydl.extract_info(url, obtain=False)
title = data.get("title", "Video")
description = data.get("description", "No description accessible.")
return f"{title}nn{description}"
This operate makes use of yt_dlp to extract YouTube video data with out downloading it. It returns the video’s title and outline, which might be summarized by the LLM.
Dealing with the Summarization Logic
if st.button("Summarize"):
if not generic_url.strip():
st.error("Please present a URL to proceed.")
elif not validators.url(generic_url):
st.error("Please enter a sound URL (YouTube or web site).")
else:
attempt:
with st.spinner("Processing..."):
# Load content material from URL
if "youtube.com" in generic_url:
# Load YouTube content material as a string
text_content = load_youtube_content(generic_url)
docs = [Document(page_content=text_content)]
else:
loader = UnstructuredURLLoader(
urls=[generic_url],
ssl_verify=False,
headers={"Consumer-Agent": "Mozilla/5.0"}
)
docs = loader.load()
# Summarize utilizing LangChain
chain = load_summarize_chain(llm, chain_type="stuff", immediate=immediate)
output_summary = chain.run(docs)
st.subheader("Detailed Abstract:")
st.success(output_summary)
besides Exception as e:
st.exception(f"Exception occurred: {e}")
- If it’s a YouTube hyperlink, load_youtube_content extracts the content material, wraps it in a Doc, and shops it in docs.
- If it’s an internet site, UnstructuredURLLoader fetches the content material as docs.
Working the Summarization Chain: The LangChain summarization chain processes the loaded content material, utilizing the immediate template and LLM to generate a abstract.
To provide your app a refined look and supply important data, we are going to add a customized footer utilizing Streamlit. This footer can show vital hyperlinks, acknowledgments, or contact particulars, guaranteeing a clear {and professional} person interface.
st.sidebar.header("Options Coming Quickly")
st.sidebar.write("- Choice to obtain summaries")
st.sidebar.write("- Language choice for summaries")
st.sidebar.write("- Abstract size customization")
st.sidebar.write("- Integration with different content material platforms")
st.sidebar.markdown("---")
st.sidebar.write("Developed with ❤️ by Gourav Lohar")
